INTRODUCTION CONTINUED
Rugged,easytouseandextremelyaccurate,theKAM®OWD®OilWaterDetectoristheidealinstrumentforcontinu-
ouslymonitoringwaterconcentrationinyourpipeline.ItisdesignedinaccordancewithAPI,ASTM,ISO,EI,UL,and
DINstandardsamongstothers.Especiallyvitalinproductionmanagement,theOWD®sensor lets you maximize oil
productionversusproducedwater.ThesimplicityofdesignandqualityofengineeringemployedintheOWD®sensor
meantherearenomovingparts.Patentedmicrowavesensorsmeasuretheconductivity,dielectric,andboththereal
andimaginarypartofpermittivityoftheuidwithanextremelyhighdegreeofaccuracy,andmeasurementisfully
automaticwithouttheneedforoperatorinterventionorsupervision.TheoutputsignalcanbesenttoFlow
Computers,SCADA,PLC’sortoaCentralControlRoomforloggingordisplayonchartrecordersormonitors.
TheKAM®OWD®sensoralsousesinternalreferencestoautocalibratefordriftcausedbytemperaturechangesof
theelectronics,theagingoftheelectronicscomponents,uidpressure,anduidtemperature.
TheKAM®OWD®owthroughmodelcanbeusedinananalyzer/densitometerloop,forprocessoptimizationwhere
anaccuratedeterminationofwaterconcentrationisimportant,anditisvitaltooptimizingthe
desalinizationprocess.Placedonthedesaltersampleline,oroneachsampleline,theKAM®OWD®owthrough
modelprovidesreal-timeinformationaboutyourdesalterperformance.
Toensurethehighestdegreeofaccuracy,theowmustbehomogenous.InstalledupstreamofyourOWD®
sensor,thepatentedKAM®SMP™StaticMixingPlateorKAM®SMS™StaticMixingSpoolcreateafully
homogenousmixtureinyourpipeline.Inlowvelocitysituations,theuseofaKAMMLMeasurementLoopmay
berequiredinordertocreateahomogenousowformeasurement.Propercalibration,alsokeytocomplete
accuracy,canbeachievedintheeldwiththeKAM®PKFPortableKarlFischerMoistureAnalyzer.
Becauseitcanbeinsertedintoyourpipeortankthrougha2",3",or4"hottap,theOWD®sensorhelpsyouavoid
costlydrainage,theneedforabypassloop,orhavingtocutasectioninthepipe.Allwettedpartsaremachinedfrom

Operator'sshouldtakeallpossibleprecautionstoavoidanymoisturefromenteringtheelectronicsenclosure.
Theenclosureshouldnotbeleftopenininclementweatherorforlongperiodsoftime,especiallyduringopera-
tionascondensationwillaccumulate.Lidshouldbetightlyscrewedshut,allconduitsshouldbesealedand
